MASK FOR CHLOROFORMING.

SPECIFICATION forming part of Letters Patent No. 429,287, dated June 3, 1890.

Anplication filed October 18, 1889.

To all whom it may concern.-

Be it known that I, CURT SCHIMMELBUSCH, medical doctor, of Berlin, in the Kingdom of Prussia and German Empire, have invented a new and useful Mask for Chloroforming, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a mask for chloroforming.

In the annexed drawings, Figure l is a plan of the mask according to this invention. Fig. 2 is a side View of the mask with the clamp raised.

Up to the present time the usual chloroformmasks have consisted of a wire frame over which there was stretched a materialpervious to the air. The repeated use of one and the same covering for several patients is undesirable in view of cleanliness and contagion of disease. WVashing and the long-continued use with chloroform, in consequence of the shrinking of the material, diminish its perviousness to the air, which is a serious mat ter, since the patient with safety to his life may only inhale chloroform mixed with air. To supply for every separate case a new specially-made covering is very expensive, and the medical manis therefore in the difficulty of either disregarding the question of expense or considering the risks of the repeated use Serial No. 327,483. (No model.)

is pervious to the air may be used without requiring any special preparation.

The mask consists of an oval grooved ring A, adapted to the shape of the face,rounded on its inner side and made of metal, and is supplied at the one side with a hinge B, and

on the other side with a convenient handle C. At the inner side of the ring A there are two wires aand b, bent in the axes of the oval. A suitable loop or clamp D is hinged at B to the grooved ring A, and is fastened with a clasp arrangement on the opposite side to the hinge.

The mode of proceeding, when using the said mask, is to turn up the loop or clamp D, to lay the pervious material over the wires a and Z9, and to fix it by shutting down the loop or clamp to the grooves of the ring A. The material overlapping the ring is then out 01f with a pair of scissors.

What I claim, and desire to secure by Letters Patent of the United States, is-

1. A mask for administering chloroform, consisting of a grooved ring curved on the inner side and provided with wires arching from one side to the other, upon which a material admitting the passage of air is laid and held by means of a loop or clamp, substantially as described.

2. A mask for administering chloroform, consisting of an open frame or ring forming the base, a movable clamp adapted to be secured to said base, and an interposed sheet of material pervious to the air, substantially as described. Y

In witness whereof I have hereunto set my hand in presence of two witnesses.
